Associated Types

type Is: ?Sized + ToOwned

The base type associated with both owned and borrowed data.

Required methods

fn as_is<'a>(self) -> Is<'a, Self::Is> where
    Self: 'a, 

Converts self into an Is<'a, Self::Is>.

Provided methods

fn into_is_cow<'a>(self) -> IsCow<'a, Self::Is> where
    Self: 'a, 

Converts self into an IsCow<'a, Self::Is>.

fn into_is_mut<'a>(self) -> IsMut<'a, Self::Is> where
    Self: 'a,
    Owned<Self>: BorrowMut<Self::Is>, 

Converts self into an IsMut<'a, Self::Is>.

If self is neither an owned nor a mutably borrowed data, it creates an owned data by cloning.

fn into_owned(self) -> Owned<Self>

Converts self into an owned data.

If self is not an owned data, it creates an owned data by cloning.

fn into_cow<'a>(self) -> Cow<'a, Self::Is> where
    Self: 'a, 

Converts self into a Cow<'a, Self::Is>.
